An indoor item management device based on uwb positioning

Abstract

The present invention relates to the technical field of item management equipment, specifically an indoor item management equipment based on UWB positioning; including a cabinet body, a cavity, a drawer, a handle and a controller; a storage box is placed on the drawer; the cabinet The body is provided with a No. 1 groove; the No. 1 groove is provided with an electromagnet, a return spring and a stopper; the electromagnet and the return spring are fixedly connected with the No. 1 groove, and the return spring is sleeved on the electromagnet. The other end of the return spring is fixedly connected with the stopper; the stopper can extend out of the No. 1 groove; the present invention supports the storage box through the stopper, and then absorbs the stopper with the electromagnet, and the storage box falls onto the drawer. The staff takes out the evidence to cooperate, so as to realize the purpose of hiding the evidence after storing the evidence, thereby preventing irrelevant personnel from being able to touch the evidence, making the storage of the evidence safer, and at the same time convenient for the staff to search. The practicability of the indoor article management equipment is enhanced.

Description

technical field [0001] The invention relates to the technical field of article management equipment, in particular to an indoor article management equipment based on UWB positioning. Background technique [0002] UWB positioning is based on ultra-wideband technology and is a wireless carrier communication positioning technology. UWB technology has the advantages of low system complexity, low power spectral density of transmitted signals, insensitivity to channel fading, low interception ability, and high positioning accuracy. Therefore, prisons, police Bureaus, detention centers and other places use UWB positioning to manage items and keep important evidence and items; however, the existing item management equipment cannot hide the stored items when storing items, so the protection of important evidence is insufficient. This makes it possible for irrelevant personnel to have access to the evidence, and at the same time cannot locate the evidence, making it inconvenient for s...

[0002] UWB positioning is based on ultra-wideband technology and is a wireless carrier communication positioning technology. UWB technology has the advantages of low system complexity, low power spectral density of transmitted signals, insensitivity to channel fading, low interception ability, and high positioning accuracy. Therefore, prisons, police Bureaus and detention centers use UWB positioning to manage items and keep important evidence and items; however, the existing item management equipment cannot hide the stored items when storing items, so the protection of important evidence is insufficient. This makes it possible for irrelevant personnel to have access to the evidence, and at the same time cannot locate the evidence, making it inconvenient for the staff to find the evidence

[0003] For example, a Chinese patent with the application number CN201922186339.6 discloses a management cabinet based on RFID technology to accurately locate items, including a main body bracket, a reader is installed on the main body bracket, and a cavity is opened in the rear side wall of the main body bracket body, a motor is installed on the rear inner side wall of the cavity, the output end of the motor is fixedly connected to a transmission shaft, the other end of the transmission shaft is fixedly sleeved with a cylindrical cam, and the protruding end of the transmission shaft is fixedly connected to On the side wall off-center of the triangular runner, the triangular runner is connected in contact with the limit frame, the outer wall of the limit frame is fixedly connected with a connecting column, and the other end of the connecting column is fixedly connected with a sliding The sleeve is slidingly sleeved with a push rod in the sliding sleeve, one end of the push rod is fixedly connected to a connecting rod, and the other end of the connecting rod is rotatably connected to a sliding rod; the bottom plate of this technical solution moves intermittently back and forth, In this way, the bottom plate can move forward, backward, up and down to achieve the purpose of convenient pick-up; however, this technical solution cannot hide the stored items, and irrelevant personnel can touch the items, which in turn causes the limitations of the solution.
